Request to have Caliper include its Adiak location in target

[aaroncblack]

I'm currently building a code that uses Caliper, and my Caliper was built with Adiak enabled.

I would like the ability to do these two use cases:

1. provide an adiak target for caliper
   OR
2. not provide an adiak target, and have caliper use the one it was built and installed against.

(I have some user requests for both of the above)

I think I've found an example from UMPIRE that does this that could be modelled off of (tagging @davidbeckingsale in case he has suggestions):

If I set up a camp target in my code, then umpire will use it. If I don't set up a camp target myself, then umpire defaults to the one it was built with.
